Connect Power BI to Azure Databricks

  • Άρθρο

Microsoft Power BI is a business analytics service that provides interactive visualizations with self-service business intelligence capabilities, enabling end users to create reports and dashboards by themselves without having to depend on information technology staff or database administrators.

When you use Azure Databricks as a data source with Power BI, you can bring the advantages of Azure Databricks performance and technology beyond data scientists and data engineers to all business users.

Publish to Power BI Online from Azure Databricks

When using Azure Databricks as a data source with Power BI Online, you can create Power BI datasets from tables or schemas directly from the Databricks UI.

Requirements

  • Your data must be in Unity Catalog, and your compute (cluster) must be Unity Catalog enabled. Hive metastore is not currently supported.

  • You must have a premium (premium capacity or premium per-user license) Power BI license.

  • You must grant the following permissions to the registered Entra ID app, Databricks Dataset Publishing Integration, that you are using to publish from Databricks to Power BI:

    • Content.Create

    • Dataset.ReadWrite.All

    • Workspace.Read.All

      Entra ID App

    For more information, see Microsoft Entra Permissions.

    Note

    Entra Admin consent is typically required for these permissions, especially for workspace and dataset-level access in Power BI. See Review admin consent requests for instructions.

  • In Power BI workspace settings, you must enable Users can edit data models in Power BI service (preview) to edit the Semantic Model after it is published. You can also edit the Semantic Model using Tabular Editor by making a connection using the XMLA endpoint.

  • If you need to enable XML write in your Power BI workspace, follow this link for instructions.

  • If your Power BI workspace uses a private link, you must update the dataset’s datasource credentials manually in Power BI.

Publish Azure Databricks tables to a Power BI dataset

  1. Sign in to your Databricks workspace and click Catalog icon Catalog in the sidebar to open Catalog Explorer.

  2. Select a compute resource from the drop-down list at the top right.

  3. Open a catalog and select the schema or tables to be published. Do not select from a hive metastore or the samples catalog.

  4. On the upper right, click Use with BI tools for a schema or Open in a dashboard for a table.

  5. Select Publish to Power BI workspace.

  6. In the Connect to partner dialog, click Connect to Microsoft Entra ID to authenticate.

  7. In the Power BI workspaces, select the Power BI workspace.

  8. In Dataset Mode, select either DirectQuery or Import.

  9. In Authentication Method in Power BI, select OAuth or PAT (Personal Access Token).

    Databricks recommends using OAuth since it allows for fine-grained access control and user-level auditing. OAuth credentials might need to be configured on the Power BI dataset settings page under Data source credentials. If you select Personal Access Token (PAT), a PAT is created on your behalf to allow Power BI to access the semantic model.

  10. In Dataset Name, select Publish as a new data set or Use an existing data set.

    When you choose Use an existing dataset, the following is true:

    • If the dataset exists, it is not overwritten. Updates only append new records in a given schema.
      • If the selected table is not part of the existing dataset, it’s added.
      • If the table was already in your dataset and new columns were added after the last update, those columns are automatically added.
      • You can choose a different storage model for the new table to create a composite semantic model.

    If you have an existing semantic model that you want update while you keep existing data connections in place, choose Use an existing dataset. If you want to create a new dataset with a new semantic model, choose Publish as new data set.

  11. Click Publish to Power BI.

  12. In 10 to 20 seconds when the dataset is published, click Open Power BI to open your Power BI dataset in a new tab.

Features and notes

  • When publishing a schema containing multiple tables, all tables with columns are published. Tables with no columns are not published.
  • Comments on a table’s columns in Azure Databricks are copied to the descriptions of corresponding columns in Power BI.
  • Foreign key relationships are preserved in the published dataset. However, Power BI only supports one active relationship path between any two tables. When multiple paths are present in the schema in Azure Databricks, some of the corresponding relationships in Power BI are set to inactive. You can later change which relationships are active or inactive in the data model view in Power BI.
  • When using OAuth or an on-premises data gateway, credentials might need to be configured under “Data source credentials” on the Power BI dataset settings page.

If your workspace is using Private Link or IP access lists, then you may need to configure a Power BI on-premises gateway.

Connect Power BI Desktop to Azure Databricks

You can connect Power BI Desktop to your Azure Databricks clusters and Databricks SQL warehouses. You can also publish Power BI reports to the Power BI service and enable users to access the underlying Azure Databricks data using single sign-on (SSO), passing along the same Microsoft Entra ID credentials they use to access the report.

Requirements

  • Power BI Desktop 2.85.681.0 or above. To use data managed by Unity Catalog with Power BI, you must use Power BI Desktop 2.98.683.0 or above (October 2021 release).

    Note

    Power BI Desktop requires Windows. An alternative for other operating systems is to run Power BI Desktop on a physical host or a Windows-based virtual machine and then connect to it from your operating system.

    If you use a version of Power BI Desktop below 2.85.681.0, you also need to install the Databricks ODBC driver in the same environment as Power BI Desktop.

  • An Azure Databricks personal access token or your Microsoft Entra ID account credentials.

    Note

    As a security best practice when you authenticate with personal access tokens, Databricks recommends that you use personal access tokens belonging to service principals instead of workspace users. To create tokens for service principals, see Manage tokens for a service principal.

  • An Azure Databricks cluster or Databricks SQL warehouse.

  4. Enter the SQL query in the parameter field and click Invoke. This executes the query and a new table is created with the query results as its contents.

Access Azure Databricks data source using the Power BI service

When you publish a report to the Power BI service, you connect to Azure Databricks using a personal access token. In the Power BI service, you can also enable single sign on (SSO) so that users can access reports built using DirectQuery storage mode by passing their Microsoft Entra ID credentials to Azure Databricks.

  1. Publish your Power BI report from Power BI Desktop to the Power BI service.

  2. Enable single sign on (SSO) access to the report and underlying data source.

    1. Go to the underlying Azure Databricks dataset for the report in the Power BI service, expand Data source credentials, and click Edit credentials.
    2. On the configuration dialog, select Report viewers can only access this data source with their own Power BI identities using Direct Query and click Sign in.

    Enable SSO for Databricks data access

    With this option selected, access to the data source is handled using DirectQuery and managed using the Microsoft Entra ID identity of the user who is accessing the report. If you don’t select this option, only you, as the user who published the report, have access to the Azure Databricks data source.

Automated HTTP proxy detection

Power BI Desktop version 2.104.941.0 and above (May 2022 release) has built-in support for detecting Windows system-wide HTTP proxy configuration.

Power BI Desktop can automatically detect and use your Windows system-wide HTTP proxy configuration.

If the proxy server does not provide a CRL distribution point (CDP), Power BI might show the following error message:

Details: "ODBC: ERROR [HY000] [Microsoft][DriverSupport] (1200)
-The revocation status of the certificate or one of the certificates in the certificate chain is unknown."

To fix this error, complete the following steps:

  1. Create the file C:\Program Files\Microsoft Power BI Desktop\bin\ODBC Drivers\Simba Spark ODBC Driver\microsoft.sparkodbc.ini if it does not exist.

  2. Add the following config to your microsoft.sparkodbc.ini file:

    [Driver]
CheckCertRevocation=0

Power BI Delta Sharing connector

The Power BI Delta Sharing connector allows users to discover, analyze, and visualize datasets shared with them through the Delta Sharing open protocol. The protocol enables secure exchange of datasets across products and platforms by leveraging REST and cloud storage.

For connection instructions, see Power BI: Read shared data.

Limitations

  • The Azure Databricks connector supports web proxy. However, automatic proxy settings defined in .pac files aren’t supported.
  • In the Azure Databricks connector, the Databricks.Query data source is not supported in combination with DirectQuery mode.
  • The data that the Delta Sharing connector loads must fit into the memory of your machine. To ensure this, the connector limits the number of imported rows to the Row Limit that was set earlier.
